MASONRY POINTING TOOL George R. Ruedi, Denver, 0010.

Application March 31, 1950, Serial No. 153,191

1 Claim. 1

This invention relates to a masonry pointing tool and has for its principal object the provision of a simple easily used device for renewing and replacing mortar between bricks and building stones in a wall.

Another object of the invention is to so construct the device that it will automatically adjust itself to different widths of mortar joints and so that it will grip and hold itself in place in the selected mortar joint.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eillciency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective view of the improved pointing tool; and

Fig. 2 is a longitudinal section therethrough, taken on the line 2-2, Fig. 1, illustrating the tool in place in a conventional mortar joint. In Fig. 2 bricks of a wall are indicated at 2| and the mortar therebetween is indicated by the numeral 22.

Figure 3 is a view of the T-shaped plunger rod employed with the pointing tool of Figure 1.

The improved tool comprises an elongated mortar pan It having two side walls and a rear end wall, the front being open. One of the side walls, indicated at l, is inclined upwardly as the rear of the pan is approached, and a portion of the end wall adjacent the side wall I I is extended upwardly to the full height of the upwardly inclined side wall I! to provide a relatively high extension of the end wall as shown at |2. The upper edge of the extension l2 of the end wall is bent forwardly to form a stop flange I3.

A tilting plate M is mounted between the side walls of the pan l upon hinge bolts IS. The plate I4 is provided with two downwardly turned side flanges I6, which fit snugly inside the sides of the pan H3 and through which the hinge bolts l5 pass. The tiltin plate I4 terminates at its forward end in a projecting lip l1 and the bottom of the pan |0 terminates in a similar projecting lip [8.

The hinge bolts are positioned relatively closer to the open end of the pan than to the closed end thereof so that the arcuate movement will be greater at the rear of the pan than at the front thereof. The upward movement at the rear is limited by the stop flang I3.

A T-shaped plunger rod I9 is employed with the tool. The plunger rod is relatively fiat and is provided with a wide head portion 20 having width substantially equal to the width of the pan Ill.

In use, the pan I0 is turned on its side and partially filled with mortar. The mortar will be held in place by the high side wall II, the high extension |2 on the end wall and the tilting plate I l. The pan is now turned to a horizontal position and the lips I7 and I8 are pressed between two of the bricks 2|. The rear extremity of the plate l4 and the pan Ill are gripped between the thumb and fingers of one hand. This causes the lips I! and I8 to tend to'move away from each other so that they will grip outwardly against the edges of the adjacent bricks 2|, as shown in Fig. 2.

The bottom and sides of the pan I0 cooperate with th inclined plate Hi and its flanges Hi to form an enclosed hopper like structure having an elongated opening communicating with the open joint between the bricks 2|. The plunger I9 is now reciprocated back and forth to force the mortar 22 through this opening and pack it into the open joint between the bricks.

It will be noted that the upper lip I? will rise to automatically accommodate any width of joint between the bricks. It will also be noted that the expandin action of the two lips I1 and I8 acts to support and hold the tool in place while the mortar is being forced into the joint. The lips I l and I8 project beyond the side of the pan It so that the latter sides can rest against the bricks 2| to prevent leakage of mortar at the sides of the tool.

While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

A masonry pointing tool comprising: an open topped pan having an open front; a lower lip projecting forwardly from the bottom of the pan beyond the open front thereof; a tilting plate; pivot means tiltably mounting said tilting plate adjacent its forward extremity on and over said pan; a lip projecting forwardly from said tilting plate above and in alignment over said first lip, one side wall of said pan extending angularly upward alongside said tilting plate and closing the space between the rear extremity of the tilt- UNITED STATES PATENTS ing plate and the pan when the latter extremity Number Name Date is at its maximum raised position; and an up- 482 369 Kruck Sept 13 1892 wardly extending rear end wall portion on said 1 467323 Jewell Sept 1923 pan extending to the maximum raised position 5 2192982 Meendsen 12 1940 said extremity- 213171292 Nash Apr. 20, 1943 GEORGE RUEDI- 2,446,143 Smith July 27, 1948 REFERENCES CITED The following references are of-record in the 19 file of this patent:
